The ionic conduction of zeolite powder in ion-exchanged water and various other solutions was investigated. H-BEA-92.5, which contained many silanol groups, showed the highest conductivity of 1.1 × 10⁻¹ S cm⁻¹ at 95 °C in a 10,000 ppm NaCl aqueous solution. After controlling the amount of surface silanol groups by calcination or dealumination, zeolites with a relatively large number of surface silanol groups showed the highest conductivity in water. The improvement of conductivity with zeolite in water was also observed for zeolite-related materials with surface silanol groups. Therefore, we conclude that surface silanol groups play an important role in increasing the conductivity of solution with zeolite in water. Furthermore, it was revealed that the mechanism of conduction was similar to the Grötthuss mechanism because of its apparent activation energy.

研究了沸石粉在离子交换水和各种其他溶液中的离子传导。含有许多硅烷醇基团的H-BEA-92.5的最高电导率为1.1×10 ^-1  S cm ^-1在10,000 ppm NaCl水溶液中于95°C下加热。通过煅烧或脱铝控制表面硅烷醇基团的量后，具有相对大量表面硅烷醇基团的沸石在水中的电导率最高。对于具有表面硅烷醇基的沸石相关材料，还观察到了沸石在水中的电导率的改善。因此，我们得出结论，表面硅烷醇基团在增加沸石在水中的溶液的电导率方面起着重要作用。此外，据揭示，由于其明显的活化能，传导机理与格罗特斯机理相似。
